High transparency and durable antifouling surfaces are crucial for Marine applications. However, achieving a long-lasting marine coating that combines both properties high transmittance remains significant challenge.

This structure leverages multistrength dynamic hydrogen bonds, including quadruple bond motif, 2-ureido-4-pyrimidinone (UPy) unit. The enhances adhesion providing additional binding sites, which facilitate interactions interfacial groups through rearrangement UPy units.

Harvesting ambient mechanical energy from the environment has gained immense interest due to its application in harvesting and active sensing. Herein, an ABO 3 class ferroelectric semiconducting material BaTiO nanoparticles are used, Antimony (Sb) is used as a dopant, which can be able enhance piezoelectric coefficient of higher level, leading increased energy‐harvesting performances. The fabricated antimony‐doped barium titanate [Sb‐doped designated (BST)] then blended with polydimethylsiloxane (PDMS) prepare composite film. Electrodes attached film on either side fabricate flexible nanogenerator (FCF‐PENG) device. FCF‐PENG device generates maximum electrical output peak‐to‐peak 28 V 1.5 μA, respectively. also shows good power density 1.6 mW m −2 at load resistance 80 MΩ. At last, real‐time impact sensor was employ wearable sensor. detects high low upon human collision tested within laboratory values recorded monitored indicator using ESP32 microcontroller ThingSpeak cloud. above analysis experiments proved that paves way toward sports healthcare rehabilitation Internet Things (IoT) devices soon.

Producing thermoplastic room temperature phosphorescent (RTP) materials with closed-loop recyclability from natural sources is an attractive approach but hard to achieve. Here, the study develops such RTP materials, Poly(TA)/Cell, by thermally polymerizing thioctic acid in presence of cellulose. Specifically, polymerized poly(TA) forms strong hydrogen bonding interactions CNF, promoting formation molecular clusters between oxygen-containing units. The as-formed generate humidity- and excitation-sensitive green emission. Red afterglow emission also obtained integrating Poly(TA)/Cell together Rhodamine B (RhB) via energy transfer process. Attributed properties, as-obtained can be molded into flexible shapes uncompromised performance. Moreover, owing alkali-cleavable properties disulfide bond cellulose successfully recycled a yield 92.3% 81.5%, respectively. As demonstrator for potential utility, used fabricate information encryption.
